Specification of Letters mat.

' vTo all whom it may concern:

Be it known that 1, CHARLES R. MORSE, a citizen of the United States, residing at Chicago, in the county of Cook and State useful Improvements in Computing-Machines, of which the following is a specification.

My invention relates to computing or adding machines, and pertains more especially, though not exclusively, to machines of this character having but ten value-keys, as distin 'uished from those machines supplied with a set of keys for each column of figures.

One object ofthe' inventionis the provision of an accumulating machine in which several of the various parts shall be formed and constructed as readily-detachable or quickly-removable units, which obviously facilitates the construction of the machine and the repair of the same.

Another feature of addin machines incorporating the advantages 0 this invention resides in the fact that in a mechanism of this character the item or amount set up on the number-wheels is visible to the operator before such amount is printed as an item on the paper slip, and before such amount is transferred to the accumulator wheels. In addition, I supply the machine with an error-key which permits the quick elimination of an error in setting up a given amount before such amount is printed or accumulated.

Another feature ofthis type of machine is the indication of the various figures of an item all in one. line in a conspicuous place directly in front of the operator.

Another salient object of the invention is the ositive actuation of the accumulator wheels from the number-wheels by means of racks and co-acting -pinions.

Another aim and purpose of the invention is the provision of a machine in which if two value-keys are pressed down or manipulated at thev same time the value ofonly one of such keys is listed, and this is indicated to the operator before the printing and accumulating. Furthermore, if two keys are depressed at the same time there is no bind ing or interfering action between-such keys.

As will be readily understood from a consideration' of the preferred and desirable embodiment of the invention hereinafter described in detail and'illustrated in the accal to manufacture. of Illinois, have invented certain new and 9 'tion.

ing operation, but also with independent in dlGiltOl numerals directly in front of the operator, which, of course, facilitates the: detection ofany error in an item before it i s listed. In addition, the mechanism .is provided with a device permitting the machine to. multiply numbers, that is, perform a succession or series of additions. This is, brought about by simply depressinga key provided for that purpose during a portion of the actuations of the, operating lever.

' These with many other new features of benefit and advantage will be readily understood by those skilled in the art from a; consideratlon of the following detailed descrip- Referring to the drawingsFigure. l is a perspective view of the complete machine inclo'sed' in a suitable housing or casing;

Referring to the drawings, it will be apparent that-the frameof the machine comprlses an open rectangular base portion 50- mounted on a plurality f rubber or other suitable feet 51. Upstanding from the front edge of such base and forming a part of the frame of the machine is a vertically-disposed plate 52 (Figs. 2467 9). Arising from the base 50 there are also provided four vertical posts 53, 54, 55, and 56 (Figs.

'234678). Mounted at the tops of posts 53 and 54 is a plate member 57 (Figs. 24-7) and at the tops of posts 55 and 56 is a similar member 58 (Figs. 23 67 Th e above-described elements constitute the main but not all of the portions of the supporting-framework of the machine, the

. are held in osition by being accommodated other parts being referred to hereinafter.

The two posts 54 and 56 have mounted in their top ends and extended longitudinally of the machine a rock-shaft or rod 59 (Figs. 2-7-9'10 l1), the other posts 53 and 55 having mounted therein, and at substantially the same height, a similar rock-shaft 60 '(Figs. 26-791011). The sliding carriage for the number-wheels reciprocates upon these two rods 59 and 60 and comprises the two blocks 61 (Fig. 17) apertured in alinement at 62 for the accommodation of the front rod 59, on which they slide. The carrier comprises also two back blocks 63 (Figs. 1718) apertured in alinement at 64 for the accommodation of the back rod 60. Mounted on the tops of these four blocks I provide a rectangular frame 65 (Figs. 29-1516) accommodating a plurality of narrow plates 66 each longitudinally-slotted at 67. Two bearings 68 are se- -viewed in Fig. 17.

cured to the tops of the side longitudinal members of the frame 65, and on a shaft 69 I rotatably adjustable in such bearings I loosely mount a plurality of number-wheels 70 (Figs. 26- 8912) corresponding in number to the columns which the machine is capable of adding. Each of such numberwheels has secured to one side a pinion 71 (Figs. 1517), and has on its outer periphery not only type or printing numerals 0 to 9, inclusive, characterized 72 in the drawing, but also indicator numerals facing in the opposite direction and characterized 73 (Fig. 15), such latter numerals being disposed between the type numerals. Each of these number-wheels 70 is of hollow forma-- tion, as shown in Fig. 19, and houses a flat spiral spring 74, one end of each of which is secured at 75 to the common shaft 69, the other end being fastened at 76 to the wheel itself, the action of the spring being such as to tend to rotate the number-wheel in a counter-cloclnvise direction as the wheel is The tension of all of these number-wheel springs may be simultaneously adjusted, either decreased or increased, by loosening the set-screws 69, turning the shaft 69 by means of its slotted end 69*, and then again setting up the screws to hold the shaft in adjusted position. In the particular machine under consideration I have shown seven of these number-wheels, so that this especial machine is capable of adding the figures of seven columns. The teeth of each gear 71 mesh with those of a sliding rack 77 (Figs. 21517'18), several of such racks being used and each hav-.

jections'or lugs 7 8 acting to maintain the f forward ends of the racks in pro-per position and permit their readyreciprocation. The more rearward portions of the racks between a j acent number-wheels 70. A horizontal plate 80 (Figs. 17 and 18) is mounted on the lower ends of the blocks 61 I and 63, such plate havingnine square holes 81 to 89, inclusive, in register with the path of travel of the enlarged foot or base piece 0f eachsliding rack 77, each of such racks being cut away at its under side along 1ts rear portion at 91. Each of the narrow plates 66 (Fig. 17 is provided with nine square holes 92 to 100, inclusive, in vertical alinement with the holes of plate 80. In order to hold the racks 77 in their normal forward position against the action of the springs 74 of the number-wheels, I provide seven right-angled catches 101 (Fig. 17 extended through the front rows of holes 81 and 92, each of such catches being surrounded by a coil expansion spring 102 which projects its top end above the aper- 1 a row for a purpose hereinafter indicated.

All of the other holes of the plates 66 and 80 are provided with sliding stops or pins, each rack having eight of such stops 106 to 113, inclusive, each stop having a coil spring 114 normally pulling the member downwardly so that it does not project above its plate 66, as is clearly indicated in Figs. and 18. Each of said sliding stops has a shoulder 115 (Fi 18) leading to which is an upper bevele or inclined surface 116. Each row of the sliding members 101' and 106 to 113, inclusive, is supplied with a rocking-bar 117 having its ends 118 and 119 downturned and pivoted at 120 and 121 on angles 122 and 123 forming parts of thesliding number-wheel carriage. At the back of themachine each of the arms 119 has connected thereto a coil contractile spring 124 (Figs. 3 1617), the lower end of which is fastened to the angle 123, and which tends to rock the bars 117 into contact with the row of sliding stops, as is clearly shown in Fig. 18, the contact of such arms 117 with the stops being above the shoulders 115 in the normal inoperative position of the parts. It should be apparent, therefore, that if one of the stop pins, 110 for example, is elevated sufi'iciently its top end will be projected into the ,path of travel of a corresponding rack, and the arm 117 will swing inwardly below. the shoulder 115 of thepin, thereby'locking the latter in rack-stopping or limiting position. If now the corresponding catch 101 is depressed against the action of its spring 102 the rack is released.

and travels rearwardly, due to the action of the number-wheel spring 74, until its shoulder 103 strikes the top protruding end of the pin 110, it being understood that the corresponding number-wheel is rotated at the same time and that the proper display and type numerals will be brought to indicating and operative or printing position when the rack is arrested in its movement by the pin.

Slidingly mounted on the front of the,-

erating mechanism for this carriage and its various elements, it will be not-icedv that upstanding from a curved bar'128 '(Figs. 24-6--7-89) forming a portion of the base or frame ,of the machine, I provide nine posts 129, in the slotted head ends of which are fulcrumed a-plurality of bent key levers 130, each under the influence of a spring 131 tending to raise the front or keyequipped portion of the same. The forward ends 131 of these-bent levers project through slots 132 in the vertical plate 52 and are supplied with the various numeral keys 1 to 9, inclusive, characterized 133, the upward movement of such forward.v portions of the levers being limited and restricted by a bar 134 fastened to the plate 52 along its top edge. The. rear upturned ends 135 (Figs. 467) of the bars 130 supplied with the numeral or value-keys 1 to 8, inclusive, are arranged in alinement, as shown in Fig. 7, and are disposed substantially directly beneath the lower ends of the first forward and back row of stop-pins'106 to 113, inclusive, when the carriage is at its limit of travel to the right as the machine is viewed from the front or top. If, therefore, the operator depresses any of the numeral-keys 1 to 8, 'inclusive, for example key #5, its rear upstanding end 135 will elevate stoppin 110 against the act-ion of its depressing spring 114 so as to project the upper end'of the stop-pin into the path of travel of the shoulder 103 of the rack farthest to the left on the carriage, and this stop-pin will be retained in such elevated position by the rocking-bar 117 swinging beneathits retaining shoulder 115.

Pivoted to the outer. faces of thetwo rear posts 53 and 55 of the machine frame at 136 and 137 (Figs. 4 and 6) are the two rearwardly-extended arms or bars 138 and 139-v .of a frame having in addition to the parts 138 and 139 the two longitudinal bars 140 and 141 (Fig. 7 the former being disposed directly beneath the front portions of the, key levers 130 and the latter having one end off-set at 142. This frame is spring-pulled upwardly by 'a pair of coil contractile springs 143 and 144 (Fig. 7 which are connected to the front of the rame and to the bar 134. The longitudinalbar 141 carries in alinement with the lever ends 135 an upstanding catch release '145 (Fig. 6) with a rearwardly-extended finger 146 (Figs. 6 and 7) disposed above the forapparent, therefore, that whenever any of the numeral or value-keys 133 are depressed,

the frame referred to including the bars 140 and 141 are also depressed, owing to the contact of the keys 130 with the bar 140.
